NAME

msgcc - C language message catalog compiler

SYNOPSIS

msgcc [-M-option] [cc-optionsoption] file...

DESCRIPTION

msgcc is a C language message catalog compiler. It accepts cc style
options and arguments.

A msgcpp(1) .mso file is generated for each input .c file. If the -c
option is not specified then a gencat(1) format .msg file is
generated from the input .mso and .msg files. If -c is not specified
then a .msg suffix is appended to the -o file if it doesn't already
have a suffix. The default output is a.out.msg if -c and -o are not
specified.

If -M-new is not specified then messages are merged with those in the
pre-existing -o file.

OPTIONS

The following options are supported:

cc-options
Specify cc style options and arguments.

-M-option
Set a msgcc option.

Specify option as one of the following:

mkmsgs
The -o file is assumed to be in
mkmsgs(1) format.

new
Create a new -o file.

preserve
Messages in the -o file that are not
in new .msg file arguments are
preserved. The default is to either
reuse the message numbers with new
message text that is similar to the
old or to delete the message text,
leaving an unused message number.

set=number
Set the message set number to number.
The default is 1.

similar=number
The message text similarity message
threshold. The similarity measure
between old and new message text is:

100*(2*gzip(old+new)\
/(gzip(old)+gzip(new))-1)

where gzip(x) is the size of text x
when compressed by gzip. The default
threshold is $__similar__$.A
threshold of 0 turns off message
replacement, but unused old messages
are still deleted. Use -M-preserve to
preserve all old messages.

verbose
Trace similar message replacements on
the standard error.

OPERANDS

The following operands are supported:

file
Specifies the name of the file on which msgcc operates.

EXIT STATUS

0
Successful completion.

>0
An error occurred.

EXAMPLES

Example 1: Using msgcc

The following example uses msgcc to extract localizable strings from
the file hello.c, marked using ERROR_dictionary(), writes them to the
file hello.mso, and creates a gencat format xxx.msg file:

example% cat hello.c

#include <stdio.h>
#include <stdlib.h>

/*
* dummy macro to avoid including
* libast headers
*/
#define ERROR_dictionary(x) x

int main(int ac, char *av[])
{
puts( ERROR_dictionary("hello world") );
return( EXIT_SUCCESS );
}

example% msgcc -o xxx -D__STDC__ -D__i386 hello.c

example% cat hello.mso
str "hello world"

example% cat xxx.msg
$ xxx message catalog
$translation msgcc 2007-09-25
$set 1
$quote "
1 "hello world"
